Since being arranged to monitor the underground by Feng Yongcheng, Ma Li and his subordinates have sighed one after another.
Huang Zhizhao and his son can operate the cyclone cannon to attack barbarians with sky-blasting thunder, and can perform meritorious deeds easily.
It's okay that he can't go to the battlefield, but he actually listens to it.
"If we were asked to go to the battlefield and fight the barbarians openly, we would be willing to do it even if the battlefield was stained with blood and horses and leather were wrapped in corpses. But now we do whatever we do," Wang Dongjiang, the deputy commander, couldn't help complaining to Ma Li.
Ma Li had a wry smile on his face. He didn't want to listen to anything from the rear, but this was an order and he had to convince his subordinates.
He thought for a while and said: "The three axes of the Hu people have failed to please, and the earth base to attack the city has failed. Of course, we must prevent the Hu people from digging tunnels and attacking."
"So that's the case, but why did you choose us?" Wang Dongjiang said angrily.
Ma Ma glared at him and couldn't help but reprimand: "This is General Feng's arrangement. Of course he has his reasons. We just obey the arrangement."
"I heard that this kind of monitoring is not something ordinary people can do." Wang Dongjiang thought for a while, shook his head, and sighed.
"So it's like this, this is going to be a big trouble." Ma Li couldn't help being shocked, and felt his head suddenly getting bigger. Looking at Wang Dongjiang, he couldn't help but ask: "How can we do it?"
"Of course ordinary people can't do it," Wang Dongjiang replied as he thought, "These must be blind people."
"Why the blind man?" Ma Li thought for a long time but didn't understand.
Wang Dongjiang glanced at Ma Li and explained: "Because the blind man is blind and can only get information through his ears."
"It does make sense," Ma Li knocked on his head, suddenly shook his head, and asked with a bitter look on his face, "But where can I find the blind man in such a hurry?"
Wang Dongjiang suddenly also patted his head and said: "Array Commander, my subordinates have remembered that blind people alone are not enough. These blind people need to be trained."
Ma Ma wanted to kick Wang Dongjiang away, but he just stretched out his foot and suddenly retracted it. He couldn't be blamed for this.
It was good enough that Wang Dongjiang could tell himself, so how could he blame him for not telling him for a while.
It seems that this is beyond my ability, and I must find my boss to solve the problem.
"Report to the general, the security group has been established for less than a year, and the Sichuan Guard Army has been established for less than three months. Where can we monitor the talents?" Ma Li said to Feng Yongcheng with a face on his face.
Feng Yongcheng thought about it and felt it made sense, but he had no choice.
He thought for a while and realized that this was not something he could solve by himself, so he used his horsepower to clean Xing Gong's house.
"So what you need is to listen to the ground!" Xixing understood Feng Yongcheng's intention.
He suddenly stood up from the chair on the desk and walked around the desk several times.
Feng Yongcheng couldn't help but be shocked. If the chief clerk couldn't do anything, what would he do about this matter?
Xi Xing suddenly patted his head, looked at Feng Yongcheng, and said, "Yes, the little saint sent someone a gift not long ago. I wonder if you need it."
He took out an object from the bookcase and saw this very strange object.
This is an oval-shaped kiln jar with a large mouth and a small belly, with a white background and engraved sauce glaze. The body of the vessel is engraved with a lotus pattern and the poem "The moon shines in the pond, and one looks at the person in the mirror."
Judging from the appearance, the mouth of the jar is on the belly of the vessel, so it is obviously not a container for water or wine.
What's even more strange is that it also has something like a wire with a bamboo tube connected to it.
Feng Yongcheng couldn't help but bowed his hands and asked: "May I ask the chief clerk, what is this?"
He is Zhao Ping's disciple anyway, and he is quite courageous.
"This is what you need to hear." As the chief clerk, Xi Xing is of course more patient and his tone is more certain.
Although he was not sure whether this was what his subordinates needed, he must be extremely sure.
Feng Yongcheng looked at this and felt a little baffled. After all, he had never seen this before.
He then bowed his hands and asked, "Excuse me, chief registrar, how to use this?"
"Put this porcelain or something like this at the bottom of the well, and the listener can hold this bamboo tube." Xi Xing said, placing the porcelain on the ground and putting the bamboo tube in his ear as a demonstration.
Feng Yongcheng asked puzzledly: "I have heard of this porcelain, why do you need this iron wire and bamboo tube?" Feng Yongcheng asked puzzledly.
"The porcelain is the receiver, the iron wire is the sensor, and the bamboo tube is the receiver." Xi Xing pointed to the three objects and patiently explained them one by one.
"Why use iron wire and bamboo tubes?" Feng Yongcheng wanted to understand. He likes to make things clear.
Xi Xing looked him over, pointed to the iron wire and the bamboo tube and said: "The iron wire is used to transmit the sound to the porcelain, and its transmission effect is the best. The bamboo tube is more effective and is very easy to make."
Feng Yongcheng thought for a while and finally understood, so he bowed his hands and said, "Thank you, Chief Secretary."
"No need to thank me, this was actually invented by the little saint. If you want to thank me, just thank the little saint." Xi Xing pointed in the direction of Chengdu and said.
It turned out that this was invented by his master. Feng Yongcheng couldn't help but be overjoyed. This master was so amazing. Not to mention music, chess, calligraphy and painting, these things involving hearing and listening were equally amazing.
He was a little embarrassed and asked: "Can I listen to this?"
Xi Xing nodded and gave him this strange thing.
Feng Yongcheng took the bamboo tube and put it to his ear, and as expected, he heard a buzzing voice.
What he felt was strange was that without the bamboo tube, the sound was almost the same as usual, but with this thing, it seemed to be amplified ten times.
"Sure enough, it is a good thing. The sound is more than ten times amplified than usual." Feng Yongcheng couldn't help but be overjoyed.
Xi Xing nodded, pointed to the iron wire and bamboo tube and said: "If there are not these two things, a trained blind man will have to do it. With these two things, even an ordinary soldier with a little dexterity can do it."
Being blind is not a problem, but finding a trained blind person is very difficult.
Well now, with Zhao Ping's invention, an ordinary person with a slightly sensitive ear can also hear it.
Ma Li led a formation of soldiers and horses, inserted the urn into the dry well, and asked dozens of subordinates with sensitive ears to monitor the ground in three shifts.
Listening to the ground is a very boring way of life, and it is very likely that you will not be able to make meritorious deeds.
And it has to be monitored all night and all day long, so you have to be extremely patient.
Are people like me just wasting time here, sitting here and waiting?
Katayoshi Weiduo is the commander in charge of the tunnels. He has continuously transported 300 barbarians to the city gate through the tunnels.
While transporting the barbarians through the tunnel, he fell into deep thought.
He remembered the conversation of the Captain and realized the importance of this matter.
Hadlucky called Katayoshi Weiduo to the base camp and told him personally: "All attacks on the city wall are just a show, and their purpose is to cover your tunnel attack."
"But the current attack on the city wall is still very powerful. The troops invested are ten times that of ours." Katayoshi Ouma said in disbelief, dumbfounded.
"Yes, this is for the Southern Barbarians to see. The purpose is to protect you." Deputy Ten Thousand Captain Siegeupon nodded and said, "You are the rare soldiers. The army has pinned all its hopes on you. .”
"It's hard for my subordinates to believe that there is such a thing." Kata Yoshio thought for a while, shook his head and answered.
Hadleki glanced at Kataiwei Duo and said: "Didn't the Han people say that what is true and what is false is true and what is false is true and what is false is true. All attacks now are just to give the Southern Barbarians a false impression. The Khanate is going all out to attack from the city wall."
"My khanate has always attacked from the ground with great fanfare. I didn't expect to learn the tricks of the Han people in one day." Katayoshi Weiduo couldn't help but sigh as he looked at the barbarians who kept attacking.
"This security group is not the Nanbarbarians of the past. All the previous offensive methods have failed." Hadeleki patted Yoshiwei Duo's shoulder and couldn't help but sigh, "Fortunately, there are some Han people who continue to give the Khanate ideas. This method is one A Han named Zhang Liang came up with it."
Katayoshi Weiduo looked at the barbarians who were attacking on the ladder. They held shields and scimitars and quickly climbed up the ladder.
It can be said that there are no more brave warriors in the world like the Khanate.
But just in the middle of the ladder, the Nanman's thunderbolts always exploded behind them, making it almost difficult for them to climb the city wall.
"The general said that we must go all out to pass through the tunnel and catch the Nanman off guard." Katayoshi Oduo said respectfully to Hadeleki.
After speaking, he felt deeply the great responsibility of his own.
Although the barbarians shouted loudly outside, there was no sound anymore when they entered the cave.
Entering through the hole was purely a sneak attack. How could he make any sound while groping in the dark?
For safety reasons, the roof defense of this lead car is particularly strong.
It adds a layer of leather fence (bamboo cover covered with rawhide) on the wooden top, then covers it with a rafter more than a foot thick, and finally covers it with the leather fence.
It also has a fireproof effect. At the entrance and exit of the car roof, fires can be quickly extinguished by using pre-prepared mud buckets, hemp bags (mops) and muddy water bags (water containers made of cowhide).
About the time it takes to advance one stick of incense, there is a faint light in the first few days, and I can see that the end is approaching.
The barbarian centurion in front came out first and listened carefully, but found no abnormal noise.
He pushed away the screen and cautiously walked toward the light.
When he came outside the light, he found that it turned out to be a dry well, and he couldn't help but be overjoyed.
If it were not a dry well, it would be very easy to make noise. Now that the well is dry, things are easier to handle.
This dry well had obviously been used by someone before, because there were gaps in the stones and footprints on both sides of the well.
He stood under the dry well and looked up at the entrance, which was estimated to be about one foot away.
The height of one foot is not difficult for this centurion, because half of the feet can be inserted into the footprints on both sides.
He took out a big knife, held it in his mouth, and climbed up from the dry well using both hands and feet.
The centurion finally came to the entrance, stretched out his head to take a look, and was overjoyed to see that there was no one in front of him.
As long as he waits for a hundred people to arrive, he can kill people and set fires everywhere in the city.
Nanman would never have thought that they would come out of the tunnel and catch Nanman by surprise.
He also thought that he was setting fire to Xi County everywhere, and the Nanman kept putting out the fire.
He even thought that he had caught a beautiful and soft little lady from the South Barbarian. This woman was far beyond what his original lady could compare to.
Thinking of this, he laughed loudly, but before he could laugh out loud, he covered his mouth with his hands to avoid exposing himself.
He suppressed his happiness, returned to the bottom of the dry well, and made a trumpet shape with his hands.
The leader of the barbarian army said to the people behind him in a low voice that everyone could hear: "There is no one here, come out quickly and kill the Nanman."
When the barbarians behind heard this, they couldn't help but be overjoyed. They all accelerated their pace and tried to get out of the dry well as soon as possible.
The centurion had just crawled out of the well when he felt a heavy blow on his head, and then knew nothing.
Ma Ma and his men each held a wooden stick and waited for the barbarians to come out of the dry well.
Ma Li couldn't help but be overjoyed when he saw the heads of barbarians emerging from the bottom of the well one after another.
On the wall, you may risk your life and death and exchange fire with the barbarians. Unexpectedly, you can still wait and see here.
He now regards the barbarians as rabbits, and whenever he sees one, he will sap him, dragging him down and waiting for the barbarian's head to pop out.
Katayoshi Weiduo walked around anxiously at the tunnel entrance, looking at the crazy attacks of the Nowhere Barbarians and at the tunnel entrance.
But now three hours have passed, and no fewer than 500 of these barbarians have entered, so something should be done.
Katayoshi Weiduo looked at the city wall. Although the barbarian attack was still as powerful, it had no real effect.
If we have to talk about the effect, it would be that it consumes a lot of Nanman's thunder, and there must be many Nanman casualties.
Of course, it is impossible to calculate the number of Nanman casualties, but it can be estimated as one hundred or one thousand.
Kata Yoshio Duo said to a centurion: "Lead a hundred people into the tunnel. Note that you are not attacking, but listening for news. If you know the news, return immediately."
